Good middle-ground:

After matching with driver:

Wait 4 minutes.

if distance from driver >= initial distance from driver:

Pop up modal asks if you would like a refund, to be matched with a different driver, or to wait.

Alternatively, if you've already waited double the estimated time, do the same popup.

This would require them admitting their estimates are baloney, which will never happen
